How to set up metrics and GA for geolending?

Question

Google Analytics

Good afternoon!
We have geolanding.
That is, the user, depending on the geolocation, gets to the pages:
/krasnodar
/rostov
/simferopol
, etc.
Poison and GoogleAds ads are set up separately for each page
. Question:
How to properly set up counters in order to conveniently analyze advertising campaigns?
Should I set separate counters for each page?
